A mobile phone, an electronic stationery device, and other electronic devices need to be provided with an electromagnetic shield in order to protect the electronic components and the like housed therein. Initially, this electromagnetic shield was made by adhering a metal plate or metal foil to the inside of the housing and case of the electronic device with an adhesive, but it may take time and labor so that the electromagnetic shield is gradually placed inside the housing. The method of plating has come to be adopted.

充分でなく問題があった。When this plating process is performed, it is not necessary to plate the front side of the housing, so masking is performed with a masking tape film or the like. However, this method requires a lot of labor for masking work and removal of the masking material. However, it is more difficult and costly for the one having a complicated three-dimensional shape, and the degree of masking is not sufficient, which is a problem.

施されたハウジングが得られる。If this masking material is adhered from the front surface side of the housing with its adhesive, the masking material will cover the surface even if the surface shape is complicated, and mask the necessary parts. Can be reliably performed. When the plating process is performed in this manner, the surface portion of the housing is surely masked and the unmasked inner portion is plated. Various methods such as electroplating and electroless plating can be used as the plating method.In the case of electroplating, the masking material can be easily removed by washing, drying, and then removing the masking material. A shielded housing is obtained.

なる。The masking material removed after the above plating treatment can be masked as it is if it is attached to a new housing to be subjected to plating treatment in the same manner as above, and thereafter, it is repeated about 5 to 7 times. Can be used. Such repeated use can reduce the cost of the masking process, save resources and reduce the amount of waste compared to the case where the masking material is discarded each time. If the above masking material is made more durable, it can be used for a longer period of time.

As shown in FIG. 3, a masking material (11) capable of covering and masking the inner part (10) of the housing (1) after the plating treatment is similarly prepared and prepared. If this masking material (11) is fitted to the inner part of the housing and the adhesive (13) provided on the flange part (12) is attached to the edge part (14) of the housing and fixed and temporarily fixed, masking will be ensured. Once done, the required surface part (2) can be painted clean and can be easily removed after painting and the masking material can be used over and over again. This exterior coating is often performed after the housing is plated, but it does not particularly matter before and after, and can be widely used when the coating is performed alone.
